One person who worked at the medical unit under both the Obama and Trump administrations said there was such a “loose control of the controlled medications” that one high-profile Obama administration official who was leaving the White House went to the medical unit for Provigil. The drug promotes alertness and helps individuals stay awake.

It was treated as a “parting gift,” the person said, and the outgoing administration official was given around 20 Provigil pills. It is not clear whether this official was ever seen by a White House doctor.

Another of the sources said they witnessed similar requests for pills from outgoing White House staffers. They also recalled being present when one Obama White House staffer came into the outpatient clinic and demanded: “I need to pick up a Z-Pak for myself and my wife.”

Z-Pak is the common name for Zithromax, an antibiotic that treats infections.
